  As described above, the envelopes described in Patent Documents 1 to 3 have one or both of the tear tape and the perforation tape provided on the flap for sealing the opening of the envelope body. Although it is excellent in that it can be opened without using a knife such as scissors or a cutter, the fact is that opening work is surprisingly difficult.

  Specifically, when opening the envelopes described in Patent Documents 1 to 3, first the end of the tape is pinched with fingers, or the fingertip is inserted into the gap between the flap near the perforation and the envelope body. However, since the end of the tape is small and the gap between the flap and the envelope body is narrow, a fine manual work is required and a lot of work is required.

  Also, picking the end of the tape with your fingers and pulling it, or inserting your fingertip in the gap between the flap and the envelope body to open it failed, and it started to tear from the part other than the tear tape or perforation, or opened. The tear often spreads from the middle to parts other than the tape and perforations.

  Therefore, the problem to be solved by the present invention is to provide an envelope that can be easily opened without using a knife such as scissors or a cutter, and does not damage the envelope body or the contents when opening. is there.

  The envelope according to the present invention is attached along the longitudinal direction of the opening at a position away from the opening of the flap for closing the opening of the bag-shaped envelope body from the opening to the upper edge side of the flap. An opening tape and perforations or break lines provided along both sides of the opening tape along the length direction of the opening tape are provided.

  In the envelope, at least one side edge portion of the flap may be provided with an auxiliary perforation line or an auxiliary fracture line extending from at least one of the perforations or the break line to the side edge portion. it can.

  In the envelope, the auxiliary perforation or the auxiliary breaking line may have a linear shape or a curved shape.

  In the envelope, in a region near at least one side edge of the flap, a part of one of the perforations or the break line crosses the opening tape to reach the other of the perforations or the break line. A break can be provided.

  In the envelope, the shape of the cut in the longitudinal direction may be a C-shape, a horizontal U-shape, or a horizontal V-shape.

  In the envelope, the flap may be provided with a display unit that indicates the position of the perforation or the break line.

  According to the present invention, it is possible to easily open an envelope without using a blade such as scissors or a cutter, and to provide an envelope that does not damage the envelope body or the contents at the time of opening.

  Hereinafter, the envelopes 10, 20, 30, 40, 50, 60, and 70 which are the embodiments of the present invention will be described with reference to FIGS. 1 to 8.

  First, the envelope 10 will be described with reference to FIG. As shown in FIG. 1 (a), the envelope 10 is a bag formed by stacking a front surface member 1 and a back surface member 2 and attaching peripheral edge portions (side edge portions 3 a and 3 b and a bottom edge portion 3 c) to each other. The envelope body 3 and the flap 5 formed by extending the upper portion of the front surface member 1 from the upper edge portion 2a of the back surface member 2 in order to seal the opening 4 of the envelope body 3. ..

  An opening tape 6 is attached along the longitudinal direction 4L of the opening 4 at a position distant from the opening 4 to the upper edge 5a side of the flap 5 in the flap 5, and the length of the opening tape 6 is provided on both sides of the opening tape 6. Perforations 7, 8 are provided along the direction. The unsealing tape 6 is attached to an intermediate portion of the space F between the side edge 9b of the adhesive surface 9 which will be described later near the opening 4 and the upper edge 2a, but is not limited to this position. Further, since the width 6w of the unsealing tape 6 and the arrangement interval W of the perforations 7, 8 are not limited, they can be set arbitrarily according to the size, material, application, etc. of the envelope 10.

  On the back surface side (back surface member 2 side) of the flap 5, a tape-shaped adhesive surface 9 that is parallel to the longitudinal direction 4L of the opening 4 in a region between the upper edge portion 5a of the flap 5 and one of the perforations 7. Is provided. Since the width of the adhesive surface 9 (distance between the side edge portions 9a and 9b) and the type of glue are not limited, the adhesive surface 9 can be arbitrarily set according to the material, size, and application of the envelope 10. When the envelope 10 is in the presealing state shown in FIG. 1A, the adhesive surface 9 is covered with a peelable protective sheet (not shown).

  After inserting the contents into the envelope body 3 from the opening 4 of the envelope 10 before sealing shown in FIG. 1A, a protective sheet (not shown) is peeled off to expose the adhesive surface 9 and the surface member 1 When the adhesive surface 9 of the flap 5 is attached to the back surface member 2 by bending in the vicinity of the upper edge portion 2a, the envelope 10 becomes the sealed state shown in FIG. 1 (b). Since the bending position is not limited to the vicinity of the upper edge 2a described above, the position near the bottom edge 3c (for example, the position of the chain double-dashed line B1, B2, etc.) is bent according to the size and quantity of the stored items. It can also be a position.
